Decades in the Making, Institut Restellini’s Amedeo Modigliani Catalogue Raisonné to Release Next Month

Why It Matters

The catalogue establishes a rigorous, interdisciplinary benchmark for authenticating modern art, offering collectors and institutions greater confidence and potentially stabilizing Modigliani’s volatile market.

Key Takeaways

• Six‑volume catalogue, 2,000 pages, 100 new authentic works.
• Combines spectrometry, carbon‑14, infrared, X‑ray with stylistic analysis.
• Aims to become standard method for art authentication.
• AI systems failed to detect known forgeries in tests.
• May tighten Modigliani market and validate previously rejected pieces.

Pulse Analysis

The Institut Restellini’s long‑awaited Modigliani catalogue raisonné represents a milestone in art scholarship. After more than four decades of research, the six‑volume, 2,000‑page work documents every known piece by the Italian modernist, adding 100 paintings newly confirmed as authentic. Restellini’s team fused cutting‑edge scientific techniques—spectrometry, carbon‑14 dating, infrared reflectography, and X‑ray imaging—with meticulous stylistic comparison and archival documentation. An entire volume is devoted to explaining this interdisciplinary methodology, positioning the publication as a potential new benchmark for future catalogues raisonnés across the art world.

The catalogue’s rigorous approach challenges the growing reliance on artificial intelligence for authentication. Restellini reports that three AI models misidentified a known fake, underscoring the limits of algorithmic analysis when detached from material evidence. By insisting that scientific data, visual assessment, and provenance must converge, the project reinforces a holistic model that reduces false positives and protects collectors from sophisticated forgeries. This stance resonates with museums and auction houses, which have increasingly demanded verifiable, multi‑layered proof before endorsing high‑value works, thereby reshaping due‑diligence standards in the market.

Beyond scholarly merit, the catalogue could recalibrate Modigliani’s market dynamics. The artist’s oeuvre has long been plagued by undocumented sales and rampant fakes, contributing to price volatility and buyer caution. By authenticating previously disputed pieces and exposing overlooked masterpieces, the publication may expand the pool of market‑eligible works, potentially stabilizing auction results and encouraging new investment. Recent record sales—$170 million for Nu couché in 2015 and $34.8 million for Paulette Jourdain in 2023—demonstrate sustained appetite, and a definitive reference could further legitimize future high‑end transactions.
